HISTORY ABOUT SPRY EVOLUTIONS

Spry Evolutions was conceived as a way for design engineer Charles Macdonald to evolve projects to be lighter, cheaper, and stronger. He has worked around the world in different motorsport
and vehicle engineering disciplines. In addition to his current commitments in the aerospace industry of south Florida, Charles is always thinking of new ways to apply the technologies
& techniques, he has spent years perfecting. Design engineering is a unique discipline, where innovation alone is not enough. Demands also include reliability, cost, and
aesthetics, while maintaining tight deadlines.

The 1998 Rutgers University Formula SAE team

TIMELINE: 1994-1998

At the Rutgers University College of Engineering, Charles achieved his Bachelor's of Science in mechanical engineering with an aerospace focus. In '97-98, he was part of formula SAE teams
that competed in the annual collegiate Formula SAE competition.

The Nissan R391 @ the 1999 24 Hours of Le Mans

TIMELINE: 1998-1999

After graduating Rutgers, Charles flew directly to England for job interviews at race car constructors & teams. He chose to join the G-Force Techologies design team, who had just
been selected by Nissan Motorsport (NISMO) to design a new Le Mans prototype for the annual 24 hour race 1999, under the leadership of Nigel Stroud. The car went on to earn
victory at the 1999 Fuji 1000 km sportscar endurance in Japan.

Stefan Gregoire's #7 G-Force GF05 @ the 2000 Indy 500

TIMELINE: 1999-2000

After Nissan did not carry on with the R391 beyond '99, Charles joined the G-Force Indy car design team, for the upcoming 2000 season. The GF05 was a new car, from the ground up,
culminating in Montoya's victory in the 2000 Indy 500 & the Louis Schwitzer Design Award. Charles spent a valuable month of May with race engineer Hayden Burville & customer Dick
Simon Racing, where Stefan Gregoire finished a strong 8th.

Reynard 02S @ 2004 Le Mans as the Zytek 04S

TIMELINE: 2001 & 2002

A move was made from G-Force to Reynard Motorsport, to join a new design team, led by Will Phillips, and tasked with a brand new car, the Reynard 02S. Sadly at the beginning of 2002,
Reynard Motorsport when into receivership, but the project continued with teams like Zytek, which eventually entered it @ the 2004 Le Mans 24 hours. The car won several European sportscar
races, but never got to live up to its full potential.

Renaul Clio V6, Platform View

TIMELINE: 2002-2003

After the close of Reynard, Charles' next move was the Tom Walkinshaw Racing Group, where he contributed to several concepts, including a Cadillac Cien production concept, as well as some final
suspension signoffs for the Renault Clio-V6. In the first quarter of 2003, TWR Engineering had to be closed.

Nissan Suspension Design Group, Hon Atsugi, Japan

TIME LINE: 2003-2005 JAPAN

2005-2007 UNITED KINGDOM

For the remainder of 2003, until 2007, Charles joined a project to design a new global platform for Nissan's Qashqai & Rogue. It involved exciting times
working just outside Tokyo, as well as transferring the work for production in the United Kingdom. Since then, the Qashqai and Rogue have sold successfully for Nissan in high
volumes.

With a view to getting back to competitive design, Charles joined the Hendrick Motorsports design team in 2007. His designs contributed to the team's championships in 2007, '08,
'09, '10, and 2013. With those accomplishments and Jeff Gordon's retirement in 2015, Charles decided it was his time to leave the team as well. He continues to follow developments
in that series and may one day contribute in a consulting or contract role in future.

Charles Macdonald joined Mooresville, NC's Riley Technologies as a Principal Engineer. After 9 seasons in NASCAR and 5 championships, it was time for a change. The excitement of IMSA
sports car racing and the Le Mans 24 Hours provided a productive design challenge. Charles was part of a team of designers led by Bob Riley, to design the Mk 30 sportscar with a goals of
winning the Daytona 24 Hours and Le Mans 24 Hours. Sadly there is too much homologation by the rulemakers, which freezes the car design. This does not leave designers much to do after
the first year the car is run, so Charles has decided to switch to aerospace and move to the beaches of Florida. The connection and love of motorsport will always be there and part of our
DNA, but it's no longer possible to watch sponsors and fans leave the motorports due to boring cars, frustrated drivers, overpriced tickets, and mediocre racing.

As of May 2017, Charles has moved to Jupiter Florida to join Parametric Solutions in aerospace design. The work is secret, and nothing more can be said.
